Fiasco (bottle) in the context of Straw

Chianti is an Italian red wine produced in the Chianti region of central Tuscany, principally from the Sangiovese grape. It was historically associated with a squat bottle enclosed in a straw basket, called a fiasco ("flask"; pl.: fiaschi). However, the fiasco is now only used by a few makers of the wine; most Chianti is bottled in more standard-shaped wine bottles. In the late 19th century, Baron Bettino Ricasoli (later Prime Minister of the Kingdom of Italy) helped establish Sangiovese as the blend's dominant grape variety, creating the blueprint for today's Chianti wines.

The first definition of a wine area called Chianti was made in 1716. It described the area near the villages of Gaiole, Castellina and Radda; the so-called Lega del Chianti and later Provincia del Chianti (Chianti province). In 1932 the Chianti area was completely redrawn and divided into seven sub-areas: Classico, Colli Aretini, Colli Fiorentini, Colline Pisane, Colli Senesi, Montalbano and Rùfina. Most of the villages that in 1932 were added to the newly defined Chianti Classico region added in Chianti to their names, for example Greve in Chianti, which amended its name in 1972. Wines labelled Chianti Classico come from the largest sub-area of Chianti, which includes the original Chianti heartland. Only Chianti from this sub-zone may display the black rooster (gallo nero) seal on the neck of the bottle, which indicates that the producer of the wine is a member of the Chianti Classico Consortium, the local association of producers. Other variants, with the exception of Rufina north-east of Florence and Montalbano south of Pistoia, originate in the named provinces: Siena for the Colli Senesi, Florence for the Colli Fiorentini, Arezzo for the Colli Aretini and Pisa for the Colline Pisane. In 1996 part of the Colli Fiorentini sub-area was renamed Montespertoli.

Italian wine (Italian: vino italiano) is produced in every region of Italy. Italy is the country with the widest variety of indigenous grapevine in the world, with an area of 702,000 hectares (1.73 million acres) under vineyard cultivation, as well as the world's largest wine producer and the largest exporter as of 2024. Contributing 49.8 million hl of wine in 2022, Italy accounted for over 19.3% of global production, ahead of France (17.7%) and Spain (13.8%); the following year, production decreased by 11.5 million hl, and Italy was surpassed by France. Italian wine is also popular domestically among Italians, who consume a yearly average of 46.8 litres per capita, ranking third in world wine consumption.

The origins of vine-growing and winemaking in Italy has been illuminated by recent research, stretching back even before the Phoenician, Etruscans and Greek settlers, who produced wine in Italy before the Romans planted their own vineyards. The Romans greatly increased Italy's viticultural area using efficient viticultural and winemaking methods.

The history of Chianti dates back to at least the 13th century with the earliest incarnations of Chianti as a white wine. Today this Tuscan wine is one of Italy's most well known and recognizable wines. In the Middle Ages, the villages of Gaiole, Castellina and Radda located near Florence formed as a Lega del Chianti (League of Chianti) creating an area that would become the spiritual and historical "heart" of the Chianti region and today is located within the Chianti Classico Denominazione di Origine Controllata e Garantita (DOCG). As the wines of Chianti grew in popularity other villages in Tuscany wanted their lands to be called Chianti. The boundaries of the region have seen many expansions and sub-divisions over the centuries. The variable terroir of these different macroclimates contributed to diverging range of quality on the market and by the late 20th century consumer perception of Chianti was often associated with basic mass-market Chianti sold in a squat bottle enclosed in a straw basket, called fiasco.

In addition to changing boundaries, the grape composition for Chianti has changed dramatically over the years. The earliest examples of Chianti were a white wine but gradually evolved into a red. Baron Bettino Ricasoli, the future prime minister in the Kingdom of Italy created the first known "Chianti recipe" in 1872, recommending 70% Sangiovese, 15% Canaiolo and 15% Malvasia bianca. In 1967, the Denominazione di origine controllata (DOC) regulation set by the Italian government firmly established the "Ricasoli formula" of a Sangiovese-based blend with 10-30% Malvasia and Trebbiano. However some producers desired to make Chianti that did not conform to these standards-such as a 100% variety Sangiovese wine, or all red wine grape varieties and perhaps with allowance for French grape varieties such as Cabernet Sauvignon or Merlot to be used. A few producers went ahead and made their "chianti" as they desired but, prohibited from labeling, sold them as simple vino da tavola. Despite their low level classifications, these "super Chiantis" became internationally recognized by critics and consumers and were coined as Super Tuscans. The success of these wines encouraged government officials to reconsider the DOCG regulations with many changes made to allow some of these vino da tavola to be labeled as Chiantis.
